Which geological hazard is amplified when permafrost underneath pipeline infrastructure thaws?

💡 Explanation

When permafrost thaws, slope instability decreases because the ice no longer binds the soil, allowing soil layers to detach along thaw slumps, triggering or amplifying landslides. Therefore landslide displacement results, rather than tsunamis, eruptions, or earthquakes, which require different geological triggers.
